The derive task failed because the system did not auto-detect a language (which is required for OCR). For future uploads I'd suggest using the beta uploader at http://archive.org/upload
aa you can choose the language at item creation rather than going back in and adding it after the item has been created and kicking off another derive task.
I've restarted the derive tasks on those and they should be completed soon.
